My two favorites in my area are Thai Gourmet in Port Jeff Station and Medford Pitta in Medford on 112.
Thai Gournet has an open kitchen and basic, though nice decor. The pad thai is wonderful as are the curries (especially massaman) and the tom kha khai is to die. If alone, you can sit at the counter and watch Artie cook, though sometimes you have to ask, because the stools are not always obvious or in place. The portions are not gigantic so have appetizers if you wish. They almost always have duck and whole fish specials. Also thai ice tea. Service is charming but can be unrelaible - the kind of place where a little patience helps. No liquor license so you can bring your own wine or beer which I always think is an advantage. Entrees are relatively inexpensive - a $25 bill for two is very possible with apps.
Medford Pitta is really a turkish restaurant. Many of the local turks eat here. Tiny and very casual dining room. Wonderful kebabs (beyti, etc.) and the red lentil soup is great. The owner makes tripe soup occasionally, though this is not to my taste, and makes his own turkey gyro which is really good. Salads are awesome and if you ask nicely, the owner Jaifer (Jeff) will read the coffee grounds re your future after you finish the potent turkish coffee. Also try the ayran, a turkish lassi (yogurt drink) that is salty - not sweet. It's not on the menu and is considered a summer drink though they usually have a pitcher under the counter. They also have turkish soft drinks and juices which are interesting.
